CHARLES JAMES APPLEBY, OF LONDON, COUNTY OF MIDDLESEX, ENGLAND.

CLUTCH.

EJZEECILFICATION forming part of Letters Patent No. 306,709, dated October 21, 1884.

Application filed July I4, 1884. (No model.)

To @ZZ whom, it may concern:

Be it known that I, CrmizLns Janes Arripnnv, of London, in the county of Middlesex and Kingdom of Great Britain, have invented certain new and useful Improvements in Clutches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. y

My invention relates to an improvement in clutches, the obiect of the same being to obtain a backward and forward motion of the coupling-sleeve concentrically with the shaft which carries it, a further object being to reduce the wear on the disks when operating the clutchsleeve, a further object being to cause the clutch to remain in gear until it is released by the attendant.

Viih these ends in view my invention consists in certain features of construction and,

combinations of parts, as will be described hereinafter, and pointed out in theclaims.

In the accompanying drawings, Figure I is a longitudinal sectional view of my improved clutch and operating mechanism, and Fig. 2 is a transverse section through the lilies l 2 of Fig. l.

A represents a shaft, either the engine-shaft or a shaft in gear with or otherwise driven by the engine-shaft, jonrnaled inA suitable bearings, a. The shaft A is provided with a central bore, af, from one end to the point where the clutch is attached, and a pin, B, is adapted to fit and slide in said bore. rlwo bevel gear-wheels, O, are loosely mounted on the shaft A, with their hubs toward each other, separated by a clutch-sleeve, D, loosely embracing hubs of the wheels and the shaft, said sleeve being provided with annular flanges d on each end, forming conical-shaped recesses d,which closely engage the conical ends of either wheel C, as the sleeve D is moved toward that wheel. The sleeve D is keyed to the pin I3 and shaft A by means of a transverse perforatiomE, passing diametrically through the sleeve, shaft, and pin, said perforation being elongatedwhere it passes through the shaft, to allow the key a limited sliding motion therein. rllhe wheels C are held against lateral outward play on the shaft by rigid collars C2, secured to the shaft or in any other convenient manner. The sleeve D is further provided withtwo longitudinal diametrically-opposte perfora-tions e,in which distance-pins F areloosely fitted, said pins proj ecting a short distance beyond the ends ofthe perforations c when the sleeve D is midway between the wheels C, and serving to hold the wheels against lateral inward play on the shaft. rlhe outer end of the pin B is provided with an annular flange, G, having a gun-metal washer, g, on one side and a gun-metal disk,g, on the other, secured in a suitable box, H, in such a manner as to allow the shaft a free rotary motion, but hold it against lateral play therein. rIhe box- H is preferably provided with a male- Vthreaded stem, k,.which works in annut, k,

suitably supported opposite the end of the shaft A. The box H is further provided with an operating-arm, L, adapted to be connected to an operating-lever leading to any desired position. A beveled pinion, M, on a shaft at right angles to the shaft A, gears with the wheels O. It will be observed that a slight turn of the box H in one direction will slide the pin B outward and canse the clutch-sleeve D to engage the cone on the right, and thereby turn the pinion M, while a slight turn of the box H in the opposite direction will throw the pin B to the left and cause the clutch-sleeve D to engage the conc on the left, thereby reversing the motion of the-pinion M.

rIhe gun-metal washer and ydisk within the box II form durable and light friction-bearings, while the gradual and positive motion imparted to the pin and clutch-sleeve by the screw serve to make this construction effective, durable, and convenient.

I do not wish to limit myself strictly to the construction herein set forth, as it is evident that slight changes may be made in the construction and arrangements of the several parts without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with two wheels loosely mounted on a shaft, a clutch located between said wheels, and distance-pins secured in said clutch, of an actuating-pin located within the shaft, and a key for securing togetherthe clutchshaft and actuating-pin.

2. The combination, with a clutchsleeve opernted by :L pin sliding,` in the bore o1" n Shaft, o1' a box embracing the hend of the pin7 the box being` provided with it screw -threaded stem adapted to engage :1- stationary nut, and means for rotating;1 the box, and thereby sliding` the pin, Substantially as set forth.`

3. The combination, with :t clutch-'sleeve operated by at Sliding rotating pin and :1- boxA elnbrneing the head ofthe pin, of zt metal washer and a metal disk interposed between the head of t-he pin and the boxv` substantially :is Set forth.

L rlhe combination, with two eone-shoiped wheels loose] y mounted on n shaft, and it clutchsleeve keyed to the shaft between the wheels,

Speeiiieation in the presence of two subserib- 2o ing witnesses.
